What server console would you recommend?

Question

Server equipment

I stand before the choice of the console for 7 servers. Some of them are controlled via USB (keyboard / mouse), 2 are better connected via PS / 2, always with remote control over IP.
All servers are placed in one rack.
It is highly desirable to be able to leave the display open and on while the rack door is closed.
Well, cheap, preferably.

Answer 1

In general, any.
Any IP console. Monitor separately - it's easier and usually cheaper (if you don't pay for each unit)

Answer 2

After 2014, when the rate rose sharply and for some projects they stopped getting into the budget, they went through the entire market and now we take consoles of only two brands.
This is the Negorack console, the one with an independent display from the keyboard and touchpad - MDR , 17" or 19" and OXCA KLB-108. And to them the IP module.
Both models should suit you.
